lo all whom it may concern.:

Be it known that l, fan'rnn H. KNOX, a citizen oi the United States, residing,` at Hannibal` in the county of Marion and State of Missouri, have invented a certain new and useful Improvement in Cement or Concrete Refrigerators, of which the followingis a specification.

My inventionA relates to a new and useful improvement in cement or concrete refrigerators, and has for its object to provide an exceedingly simple and eiiective device of this character which will be water prooi', havingno wooden parts to rot from dampness nor metal parts exposed to the destructive parts of the elements. v

Another object of my invention is to construct a refrigerator which will be reason'- able in cost and one which will he strong in construction, so that it Will last a very great length of time. n

A still further object of my invention is to construct a refrigerator of very poor conductivity so that-the heat from the outside atmosphere will he kept out, While the cold air Within the refrigerator will remain.

iVith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set Jforth and then specifically designated bythe claim,

in order that those skilled in the art to which this invention appertains may un will describe its construction in detail, re erring by letter" to the accompanying drain ingforming a part of this specification, in Which- Figure l is a. view partly partly in elevation of a refrigerator made in accordance with my improvement.. Fig'. 2, a longitudinal sectional view at the ihrem-a1 of Fig l, and Fig'. 3, a section at the line y/-y of Fifi'. l looking in the direction of the arrows.

ln carrying' out my invention as here embodied, A represents 'the back vall, and B the sides thereof, which have the lugs C 'formed therewith, on which rest the shelves ior the` reception ot articles to be placed in the refrigerator. i

D is the bottom, and E the partition dividing the inside ot' the refrigerator into and the ice compartment G. said partition also acting;` as

This parthe lioor of the ice compartment.

in section and l l tition has a .number ot' upwardly projecting ridges H. the central ridge having a groove l formed beneath it, which has a cominunication with the ice chamber thereof, the openings .i running diagonally through one of the ridges H, so that its upper end will enter the ice chamber a short distance above the upper surface of the partition E. This .allows the cold air to pass downward into the food compartment F, but its upper end being above the level of the partition E or the l'loor of the ice compartment G, the Water from the ice cannot. pass through said opening, hut must find its way to the drain K hy passing through the groove K', said drain being formed in the back of the rel frigerator and passing out at some concourse it. is understood that the partition E will slant slightly to the rear or toward the drain K, so that the Water from the ice will not remain in the ice compartment. in the one edge of which is formed the upwardly extending Walls M, said walls reaching almost to the top of the ice compartment. This causes compartment to pass upward through the refrigerator and the walls iii, and over the top of said walls whe-.re it 'viiill come in contact with the ice which Willeool it and cause it to pass downward through the openings J and the `groove 'I into the food compartment- F, and this circulationof air will continue as long as there is ice in the ice conipartment.

To the top of the refrigerator is hinged the lid N by means of the hinges (E, said lid having a rahhet l formed around its outer edge which rests upon the walls of the refrigerator, thereby forming a comparatively tight joint or closure. To the 'front oil the refrigerator is hinged the door Q hy means or' the hinges R. stationary knuckles S of which are castin the sides oi the refrigerator, and the knuckle S cast in the door. l door has a a-hbet T formed around its edge which rests upon the side walls, bottom and partition, so that a closure is formed which will prevent the passage of air into the coinpartnient. At the front of the ice compartment may be hinged a door, as 4indicated by U, or this may be a permanent front, as the manufacturer may desire.

V represents the casters,

the pintels W et vement point in the lower end thereof. OfA

the warmer air from the foodslots L andthe space between the side of the e This partition E is also formed the slots L, at

rie

partition the centred one of which is provided with diagonal openings forinlng a which are east in the refrigerator so as to l communication between the two compart- I prevent thenrbecoming loose or dropping out. K Having thus fully described my invention, 5 what I claim new and. useful, is

In a refrigerator of cement, a body having a drain formed in the back thereof, a partition formed integral with the side walls of i the body for dividing the inside into an ice vWitnessses: 10 compartment and a' food compartment., und i JNO. S. DmRKES,
